Set WLAN_OFF_L to open drain

2013-09-24T01:32:51+00:00

On bolt this pin is connected both to the PCH and the EC.
As designed, it was intended for both parts to treat this
as an open-drain circuit.

Support compiling with chipset task disabled

2013-09-23T21:26:29+00:00

For bringup, we need to be able to compile a binary with the chipset
task disabled.  Chipset functions should be stubbed to do nothing in
that case.

stm32: Fix polarity of charger interrupt

2013-09-23T19:23:58+00:00

The charger interrupt is active-low.  Snow and Spring properly
triggered on falling (asserting) edge, but Pit (and Daisy/Puppy)
didn't.  Fix those boards, and rename the signal to end in _L so we
don't make that mistake again.

TEST=unplug/replug AC adapter on pit; see debug output as follows:
	[batt] state charging -> idle0
	Charger IRQ received.

Record average runtime and delay of hooks

2013-09-23T06:10:32+00:00

In additional to recording the maximum runtime and delay, let's also
keep track of the moving average. The average is calculated by:
    New_Avg = (Old_Avg * 7 + New_Val) / 8
every time the hook fires.

The average values are only accurate for hooks that fire enough times,
but it won't be useful anyway for a hook that only fires just once or
twice.

Also, show warning if HOOK_TICK or HOOK_SECOND fires more than 10% late.

BUG=chrome-os-partner:21801
TEST=On Kirby, check average values are sane.
TEST='waitms 800' and see warning of HOOK_TICK firing late.

cleanup: move test mocks to board/host and remove unused mocks

2013-09-19T23:30:03+00:00

Now that we have a better test framework in place, mock
implementations go in either chip/host/ or board/host/, depending on
whether they're mocking chip or common/board functionality.  Move the
remaining mocks there.  Also, several mocks were neither compiled nor
used, and haven't kept pace with other refactoring; delete those.

cleanup: move board-specific battery files to board dirs

2013-09-19T00:41:12+00:00

The battery files contain board-specific constants and a few small
methods like battery-detect and battery-cut.  Most of these aren't
reused across platforms.  The battery files have also been cleaned up
so those board-specific constants basically all that's left in them.

Where a file is used by a single board only, move it to
board/(boardname)/battery.c.  Batteries used by more than one board
(e.g. battery_link.c used by both link and bolt) are still in
common/battery_*.c, since that's cleaner than duplicating the file in
each board's directory.

No code changes, just moving files.
